    switch (Item.getitemid ()) {

    case Menu.first + 1:

      toast.maketext (This, "delete menu was clicked", Toast.length_long). Show ();

      break;

    Case Menu.first + 2:

Three, custom style

<?xml version= "1.0" encoding= "Utf-8"?> <linearlayout xmlns:android=
"http://schemas.android.com/apk/" Res/android "
  android:orientation=" vertical "
  android:layout_width=" fill_parent "
  android:layout_" height= "Fill_parent"
  >
<gridview
     android:id= "@+id/gridview" android:layout_width= "Fill_"
     Parent "
     android:layout_height=" fill_parent "
     android:numcolumns=" 4 "
     android:verticalspacing=" 10dip "
     android:horizontalspacing=" 10dip "
     android:stretchmode=" columnWidth "
     android:gravity=" Center "
     />
 
</LinearLayout>

First customize the menu interface, I am the GridView to include the menu items, 4 columns, 3 rows

<?xml version= "1.0" encoding= "Utf-8"?> <relativelayout xmlns:android=
"http://schemas.android.com/apk" /res/android "
  android:id=" @+id/relativelayout_item "
  android:layout_width=" fill_parent "Android:layout_" height= "Wrap_content"
  android:paddingbottom= "5dip" >
  <imageview android:id= "@+id/item_image"
    Android:layout_centerhorizontal= "true" android:layout_width= "wrap_content"
    android:layout_height= "WRAP_" Content "></ImageView>
  <textview android:layout_below=" @id/item_image "android:id=" @+id/item_text "
    android:layout_centerhorizontal=" true "android:layout_width=" wrap_content "
    android:layout_height=" Wrap_content "android:text=" Options ></TextView>
</RelativeLayout>

The realistic style of a menu item, an icon and a text.

If you set the view the first time you open it, the Menudialog view is displayed directly.

Private Simpleadapter Getmenuadapter (string[] Menunamearray,

Adds a menu item to the menu.
